Calibration problem

Hi
Each time it is restarted, SC2 is decalibrated and must recalibrate.
What is wrong?

Regards

Do you mean that the center point is wrong, or that the wheel moves slowly left-right-left-right on startup?

so after restarting the steering wheel is not straight

You can choose to save the calibration for this session or for every restart. Choose the latter option.
